Known Issues

Asnychronous PreReceiveRepositoryHooks do not work with subversion

The following example will fail to log the changesets.

import com.github.legman.Subscribe;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import sonia.scm.plugin.Extension;
import sonia.scm.repository.Changeset;
import sonia.scm.repository.PreReceiveRepositoryHookEvent;
import sonia.scm.repository.api.HookChangesetBuilder;

@Extension
@EagerSingleton
public class DemoHook {

  private static final Logger LOG = LoggerFactory.getLogger(DemoHook.class);

  @Subscribe
  public void handleEvent(PreReceiveRepositoryHookEvent event) {
    HookChangesetBuilder changesetProvider = event.getContext().getChangesetProvider();
    for (Changeset c : changesetProvider.getChangesets()) {
      LOG.warn("received {} hook for changeset: {}", event.getType(), c.getId());
    }
  }

}

This is because of the transaction management of subversion. The scm-manager subversion provider becomes a transaction id for the changes of the current push, but the transaction has finished before scm-manager can resolve the incoming commit. To solve the issue, we could use a synchronous subscription instead e.g.:

import com.github.legman.Subscribe;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import sonia.scm.plugin.Extension;
import sonia.scm.repository.Changeset;
import sonia.scm.repository.PreReceiveRepositoryHookEvent;
import sonia.scm.repository.api.HookChangesetBuilder;

@Extension
@EagerSingleton
public class DemoHook {

  private static final Logger LOG = LoggerFactory.getLogger(DemoHook.class);

  @Subscribe(async = false)
  public void handleEvent(PreReceiveRepositoryHookEvent event) {
    HookChangesetBuilder changesetProvider = event.getContext().getChangesetProvider();
    for (Changeset c : changesetProvider.getChangesets()) {
      LOG.warn("received {} hook for changeset: {}", event.getType(), c.getId());
    }
  }

}

Percent signs are not encoded correctly

If a branch, path or file with a percent sign in its name is called directly via url, the server responds with an error 400. This is due to incorrect encoding of percent signs in the URI, which itself is used for client side routing.

It also applies to forwarding in editor-plugin after creating a file with the above-mentioned properties. The actual file is created correctly though.
